Ok, from the apple menu, select about this mac, and then click on the system report button. That should launch the System Information application. At the bottom of the hardware list is USB. Select that. It will show you what is currently plugged into your USB ports. Plug in your usb to ethernet dongle and let us know if it shows up. Also, have you tried different USB ports on the laptop? And with your laptop plugged in to power?

First party dongles usually always work. Having said that your USB to Gigabit ethernet adapter is made by who? Also which Mac are you using this with. That would help us troubleshoot your issue.

Adapter is J5create model jue130. It worked before I upgraded to Big Sur. Went to J5create website to get new driver and found this message "Attention macOS® 11 Big Sur users: j5create USB™ Display and USB™ Ethernet adapters are not currently compatible with macOS® Big Sur 11.
To avoid loss of functionality with the j5create USB™ Display and USB™ Ethernet adapters, we advise all Mac® users to delay updating to macOS® Big Sur 11."
When will it be compatible?
You can do nothing, except waiting and hoping for new drivers to be released.
Apple thinks we have to change our third party devices every year, think about usb wifi adapter.
Big sur is still a big mess and Apple is going to close more its os and hardware, several developers left Apple, so many troubles to make things compatible every year.
Same here ! Told by apple support to update the drivers, it’s plug and play ! Then told to buy Apple product instead 3rd part ...
I'm using a 2018 MacBook Pro and the adapter is from UGreen. It worked fine until i upgraded.
I'm on a MacBook pro late 2013. I tried looking for it under usb and it's not showing up.
Hi Paul, The USB list tells me that the device is plugged in, however still not working ?
Thanks to everyone for the info!
That means you need updated drivers. At least the hardware is seen.
